A year and a half after helping to launch a wave of consolidation with its purchase of a Silicon Valley chip company, Avago is reportedly looking at two other Bay Area semiconductor manufacturers for possible acquisitions.

Reuters reported Thursday afternoon that the Singapore-based chip company has reached out to at least three potential acquisition targets, including two of Silicon Valley’s largest semiconductor manufacturers: Xilinx and Maxim Integrated Products, both based in San Jose. Tokyo-based Renesas is also on Avago’s list of targets, according to the report.

“It’s our policy not to comment on rumors or speculation,” Maxim spokeswoman LuAnn Jenkins Walden said in an email Thursday. Xilinx also declined to comment.

Analysts say that the maturation of the semiconductor business has created a need for larger companies, as the decline of the personal computer industry creates growth issues and the lower margins of the mobile-device industry squeeze profits. By teaming up and cutting staff, chip companies are realizing economies of scale to fight those trends and expand their potential customer base.

Maxim was actually out in front of the trend, purchasing Fremont rival Volterra Semiconductor for more than $500 million in 2013. The growth in revenues from that purchase has made Maxim and Xilinx very similar companies: Xilinx was the seventh-largest chip company in Silicon Valley in 2014 with $2.43 billion in sales, while Maxim was 8th with $2.4 billion. Both are among the 35 largest public technology companies in the Bay Area.

The two companies are different in terms of products. Xilinx, an Altera rival, helped pioneer malleable chipsets known as field programmable gate arrays, or FPGAs, which have proved popular in everyday gadgets connected to the Web, referred to as the Internet of Things. Maxim is a specialist in analog chips, which are used in cars, communications equipment and data centers.

Shares in Xilinx and Maxim jumped after the report hit Thursday afternoon. Xilinx closed with a 2.9 percent gain at $44.99 that pushed its market valuation to $11.6 billion; Maxim increased 4.9 percent to $34.10 a share, which made its market capitalization $9.7 billion. Reuters reported that Avago is willing to spend more than $10 billion on a takeover.

Apple gained 2.3 percent to $128.95 despite a report that its HomeKit software platform for the Internet of Things would be delayed. Fortune reported that HomeKit, which Apple announced nearly a year ago, would not launch until later this summer, but Apple disputed that report after the market closed and said the first HomeKit devices would hit stores in June as planned.”We already have dozens of partners who have committed to bringing HomeKit accessories to market and we’re looking forward to the first ones coming next month,” Apple spokeswoman Trudy Muller told the Wall Street Journal. After announcing HomeKit at last year’s Worldwide Developers Conference, Apple is expected to introduce a new streaming-music service at this year’s WWDC, and a Thursday report said Apple will bring back elements of Ping, a social-media experiment in iTunes that was not well-received.
